Automating Publications with Claude, Canva, and n8n
Every business that runs a social media page knows the same repetitive cycle. Pick a topic. Write a caption. Design a graphic. Post it on schedule. Repeat tomorrow. Multiply that by every campaign, every seasonal push, every recurring content series, and it becomes a real operational cost, not just [...]
AI Ethics Explained: How to Use Artificial Intelligence Responsibly
Have you ever used ChatGPT to help explain a difficult topic? Maybe you've asked Gemini to summarize a lengthy article, generate ideas for a school project, write an email, or even use Claude for brainstorming concepts. If you're a student, you've probably wondered: "Is it okay to use AI [...]
Fine-tuning an LLM for natural Tagalog speech
If you're an ML engineer or a technical lead planning to pre-train a large language model (LLM) for Tagalog or Taglish, how do you start? In this article, we walk through the process of defining a target voice, building a data pipeline, running a QLoRA training experiment, and evaluating [...]
Building Diffender: A Serverless AI Security Reviewer for GitHub Pull Requests with Amazon Bedrock
A pull request can pass its tests, satisfy its acceptance criteria, and still expose a production credential in one line of code. Diffender is an Amazon Bedrock pull request reviewer built to identify that kind of risk before the change reaches the main branch. However, human review remains essential, [...]
AWS Certification Maintenance: Recertify Without an Exam
Many AWS-certified professionals face the same challenge every few years: preparing for another certification exam while balancing work, projects, and personal commitments. While certifications remain a valuable way to validate cloud expertise, the traditional recertification process can be time-consuming and stressful. To address this, AWS has introduced a new [...]

CI/CD Crash Course: From Junior to Senior Developer
Continuous Integration and Continuous Delivery/Deployment (CI/CD) is the backbone of modern software teams. It's not just a buzzword for your resume — it's the automated pipeline that takes code from "it works on my machine" to "it works in production, reliably, every time." Understanding CI/CD deeply, not just using [...]
Everything You Need to Know About Harness Engineering
AI agents can now write code, browse the web, and run for hours without a human watching. Ask one to build a feature, and it might open ten files and call five tools. It can make a hundred small decisions before it ever shows you a result. That is [...]

Build a Model-Agnostic AI Text Summarizer Web Extension

Browser extensions are a great way to bring AI directly into your everyday workflows. Instead of copying text into external tools and websites to be summarized, you can do it right on the page. In this tutorial, we'll build a lightweight, model-agnostic Chrome extension that summarizes selected text using AI. With a simple right-click, users can send any highlighted text to an AI model of their choice and instantly view a concise summary in [...]

AWS Lambda Managed Instances: Serverless Simplicity with EC2 Control

AWS Lambda Managed Instances marks a significant evolution in serverless computing. For years, standard Lambda was the default for running code without infrastructure management, but it offered limited control over the underlying hardware. This new capability changes that by combining serverless simplicity with Amazon EC2 flexibility. Announced at AWS re:Invent 2025, this feature enables Lambda functions to run on designated Amazon EC2 instances. You choose the hardware configuration, while AWS manages the infrastructure. [...]

How to Generate Simple Document Embeddings with Python

Document embeddings are one of the simplest ways to give machines an understanding of text, and in our previous article, Document Embeddings Explained: A Guide for Beginners, we explored how they turn entire documents into dense numerical vectors that capture meaning and context. Now that you understand what embeddings are and why they’re useful for tasks like semantic search, classification, and clustering, this tutorial will show you how to generate them in practice using [...]

Open Cybersecurity Schema Framework (OCSF) and Amazon Security Lake

Amazon Security Lake is a managed service that collects and stores security logs from AWS services, on-premises systems, and supported third-party tools. It automatically converts all incoming data into Apache Parquet and formats everything using the OCSF schema. This setup allows different kinds of security logs to follow one consistent structure instead of having separate formats. With this unified approach, teams no longer need to decode or reorganize data manually because Security Lake handles [...]

Can Gemini 3 Replace My AI Toolkit?

I've always approached AI with one mindset: use whatever tool gets the job done fastest and cleanest. I'm not loyal to one model, one company, or one ecosystem. I switch between tools depending on what my day looks like. In school, that might mean summarizing academic papers. At work or during self-study, that might mean debugging code or reviewing a cloud diagram. For daily life, it might just mean drafting an email or organizing [...]

AWS Vector Databases Explained: Semantic Search and RAG Systems

The generative AI (GenAI) revolution has transformed how organizations extract value from their data. While large language models (LLMs) demonstrate remarkable capabilities in understanding and generating human-like text, their true enterprise potential is unlocked only when they can access proprietary, domain-specific information. This necessity has propelled vector databases from a specialized niche into an essential pillar of modern AI infrastructure. But First, What Are Vector Databases? A vector database, as its name suggests, is [...]

Self-Hosting Judge0: A Step-by-Step Guide Using Amazon EC2, Lambda, and S3

Judge0 is a powerful, open-source code execution system widely used by online coding platforms to run programs in secure environments. However, while it is often accessed as a third-party service, self-hosting Judge0 on AWS significantly grants you complete control over configuration and security. In fact, this level of ownership is essential for handling sensitive data or customizing language support. Moreover, self-hosting enables greater scalability, thereby allowing you to adapt the system as your requirements [...]

The Cash Cow + Investment Model: A Career Blueprint from Tutorials Dojo’s CEO

Imagine spending weeks building a course, only to watch it fail. That’s exactly what happened in 2019 to the founder of Tutorials Dojo, Jon Bonso. He had spent weeks building a React Native course. He recorded, edited, and re-recorded, hoping people would buy it. However when it finally launched, the effort didn’t match the reward. It was one of those career-defining moments where you ask yourself: “Am I even in the right industry?” Instead [...]

AWS Strands Agent SOPs – Your Natural Language Agentic AI Workflow Tool

If you're someone whose work involves AI automation or a developer, you'll know that Modern AI agents are powerful but notoriously difficult to guide with consistency. You put the same thing in twice, you get two drastically different results. There are two ways of driving Modern AI agents: Code defined workflows Fully model-driven agents Code-defined workflows offer precision but require heavy reengineering to update. Fully model-driven agents offer flexibility but can behave unpredictably. Agent [...]
